Well I had the same issue last weekend and stopped playing because I simply couldn't get into the Sol System. Now it seems I have the same issue. I've been on the loading screen for Sol for over 30mins! and this is my third try to get in.
Well it doesn't get any better, 4th attempt and still waiting around 30mins with no luck.
I heard tale, although not seen any official post, that US subscribers get priority access. Now I have no problem with that if it means I'm waiting a few mins extra during peak times but if I can't get in and it's because of that, then something is clearly wrong.
I'm running from UK/Steam.
I'm not too annoyed nor impatient as I expected many issues during the start of this, like most mmo's. I just hope it's a recognised issue for some people. The fact that many aren't posting this issue worries me that it's not something that will be addressed in due coarse.
